Vedclass · Answer

(D) The correct pair is $D$. $1$. Habitat loss and fragmentation is the most important cause driving animals and plants to extinction. The most dramatic example is the tropical rainforests,often called the 'lungs of the planet',which are being cut and cleared for agricultural purposes or for conversion to grasslands for raising beef cattle. $2$. Co-extinction refers to the extinction of a species when its obligate partner species becomes extinct (e.g.,host-parasite). $3$. Alien species invasions involve the introduction of non-native species like $Parthenium$ (carrot grass) or $Eichhornia$ (water hyacinth) which cause environmental damage. $4$. Over-exploitation refers to the excessive use of natural resources,such as over-harvesting of marine fishes.
